Wrapped long lines in an error message, and fixed two bugs:
1) rndc would crash if rndc.conf could not be read 2) rndc running in named.key mode required a working DNS to resolve the default server name "localhost", causing a chicken-and-egg problem when using rndc to fix a broken DNS. Fixed by changing the default to 127.0.0.1. This will probably offend some IPv6 people.
